A method to interrogate changes in transfer matrices regarding damage localization is extended to cases where these changes cannot be experimentally obtained because the input is not known deterministically. The extension is realized by noting t[...]

This paper shows that the mechanical behavior of concrete materials can be described by a nonlinear unified strength criterion which requires four independent parameters for model calibration. The criterion covers all the area from spatially mob[...]
